Thirty-eight days after killing the infamous Ice Truck Killer in Season 1, Dexter Morgan still has problems. Sgt. Doakes remains convinced that Dexter has something sinister to hide. His sister Debra has moved into his apartment, unable to get over the pain of nearly being murdered. And his girlfriend Rita suspects Dexter of framing her ex-husband. Dexter's difficulties multiply when evidence of his own murderous activities surfaces in Miami — the city has a new serial killer to focus on. Frank Lundy, an FBI agent flies in from Washington to head up the search, and forms a taskforce whose sole purpose is to uncover the identity of the newly dubbed "Bay Harbor Butcher."
